Abstract: ISO (1995-2001) was an important ESA legacy mission that observed the sky in the infrared wavelength. This satellite performed around 30,000 science observations, including parallel and serendipity modes of the instruments (observational modes in which an instrument could observe while another instrument was prime). Spectral data is still a reference in infrared astronomy and ISO data have special interest these days as it is being used by scientists e.g. to help on the preparation JWST proposals, both because of the energy range that ISO covered and for transient data identification. The ISO data archive was the first archive produced at ESAC by the Science Archives Team, using, at that time, powerful technologies like Java Applets and three-tier-architecture. 25 years from is launching, the archive has been re-engineered with new technologies, including a powerful user interface (GWT), command line access, Virtual Observatory protocols (SIAP, SSAP, TAP, ObsCore) and, also, an astroquery module to allow the access using astronomical python libraries. This new archive has, also, accurate geometrical queries with detailed footprints that can be displayed on an Aladin Lite visualizer. As part of the user interface capabilities, dynamic visualisation is offered for spectral data (highcharts) and images (js9). Also, apart from the pipeline data, data processed by expert users (HPDP - Highly Processed Data Products) can be queried and downloaded from the interface. Finally, publications linked to ISO observations can be also found providing deep access to all the scientific treasure that this satellite produced.
